Final answer:
In manufacturers' data manuals, data selectors are often referred to as multiplexers, which is an electronic device that selects one of several input signals to forward to a single output line.
Step-by-step explanation:
Manufacturers' data manuals generally refer to data selectors as multiplexers. A multiplexer, often abbreviated as MUX, is an electronic device that selects one of several input signals and forwards the selected input into a single line. Multiplexers are used in situations where the need to carry data on a single channel or cable is present, in order to minimize the number of wires required to communicate multiple signals.
The typical multiplexer has several input lines, but only one output. The selection of which input will be forwarded to the output is controlled by separate input lines known as select lines.
